Scan Your Entire Environment For GHOST With GuardRail

This week Qualys announced a vulnerability in certain versions of glibc that is now being called GHOST. The vulnerability allows remote execution of code by calling gethostbyname() and is considered critical. We won't cover what others have already said: you can read the original Qualys post here, a summary from ZDNet here, and advice on updating your OS version here. If you aren't sure what version of glibc is used on every one of your Linux machines, read on. We have created a one-click solution for validating the security of all your nodes.

What's new in DevOps? Anything?

There's no doubt that in 2015 DevOps is real, and strong, and it is your friend. If you aren't investing in DevOps now, you should be. Ask anyone, or just be quiet while they yell at you, and you'll hear that you need DevOps.

We love the principles of DevOps, we take it seriously in our own development practices at ScriptRock, and we design our software to be equally usable by Devs and Ops to solve their shared problems. We've been listening and contributing to the DevOps conversation for a few years. Here's the problem: almost nothing has changed in that time.

GuardRail provides a really easy way to validate that the update has been successfully applied and the registry keys deleted. In addition to giving you validation that patches have been applied now, our Schannel check can be run automatically to protect against regressions.
